Model PCI/PCIe 79G5

PCIe I/O & Comm Board

Three I/O and communication function module slots —
Over 70 different modules to choose from

NAI's latest generation single-slot, half-size PCIe board, the 79G5 can be configured with up to three NAI smart I/O and communication function modules. Ideally suited for high channel density and combined Multifunction I/O requirement systems, the 79G5 delivers off-the-shelf solutions that accelerate deployment of digital and analog I/O, position control and measurement/simulation and communication interface applications.

Adaptable Architecture

NAI’s Configurable Open Systems Architecture™ (COSA®) offers a choice of over 70 smart I/O, communication, and Ethernet switch functions, providing the highest packaging density and greatest flexibility of any multifunction I/O board in the industry. Preexisting, fully-tested functions can be combined quickly and easily in an unlimited number of ways. Each I/O function has dedicated processing, unburdening the system Single Board Computer (SBC) from unnecessary data management overhead.

Software Support Kit (SSK)

The 79G5 includes SSKs to support multiple operating systems. In addition, SSKs are supplied with source code and board-specific library I/O APIs to facilitate system integration.
